This Phase 2 SBIR proposal presents an architecture for wireless microsensor networks that provides improved information assurance (IA). It addresses both traditional computer network security threats (e.g., eavesdropping, masquerade and forgery) and also microsensor-centric IA threats such as denial-of-service attacks, battery exhaustion, sensor tampering/spoofing, and adversarial movement of sensors. It also covers other important IA issues such as network reliability, network availability, long-term maintainability, and the integration with the DoD's strategic backbones and tactical Intranets. Finally, SRC's modular open system architecture is based on industry standards, uses common hardware and software, and also provides a dynamically-configurable microsensor network with improved information assurance that can continuously evolve as new technologies emerge. The ability of multimode sensors (or collections of single-mode sensors) to detect adversarial movement/spoofing of the deployed microsensors is a key technology that will be demonstrated during this proposed Phase 2 effort. Second, "stovepipe avoidance" requires a conscious and concerted effort from the earliest stages of system design and deployment. Binary-encoded Extensible Markup Language (XML) technology satisfies that critical requirement, and will be the other prime focus of the Phase 2 prototyping effort. Third, a standards-based method for implementing Multi-Level Precedence and Preemption (MLPP) concepts is always a key concern in any of the DoD's low-bandwidth tactical-communications system. The Phase 2 test-bed will also demonstrate a wireless Internet Protocol (IP) network that provides multihop routing and forwarding of IP datagrams, thereby leveraging existing work at SRC.
